Ferrari 456 M GTA Parts & Accessories

The Ferrari 456 M GTA pairs the updated Modificata exterior of the 456 M series with the four-speed automatic transmission, providing the revised styling of the M body with the effortless long-distance driving convenience of the automatic gearbox in Ferrari's final iteration of the 456 platform. The M GTA was produced alongside the manual M GT from 1998 through the end of 456 production in 2003, and it represents the most refined and comfortable grand touring configuration in the 456 range. Owners maintaining a 456 M GTA work with the M body specification's updated exterior components alongside the GM automatic transmission's specific service requirements, in addition to the 5.5-liter V12's standard maintenance schedule. The combination of V12 performance, automatic transmission convenience, and the updated Modificata styling makes the 456 M GTA a compelling grand touring value for buyers who prioritize relaxed driving over manual engagement.

Popular Upgrades

Timing belt replacement kits, water pump assemblies, and cam cover gaskets are the essential V12 service items for the 456 M GTA, with the five-year replacement interval applying regardless of the automatic transmission configuration. GM automatic transmission fluid kits, filter replacements, and valve body service components are the drivetrain-specific service items that distinguish the M GTA from the manual M GT. Bosch Motronic fuel injection components including fuel pressure regulators, idle speed controllers, and throttle position sensors address running quality issues on aging M GTA systems. Suspension bushings, rebuilt shock absorbers, brake caliper rebuild kits, and braided stainless lines support chassis and brake maintenance appropriate for the M GTA's performance level.

Performance and Handling

The 456 M GTA provides the same 442-horsepower V12 performance as the manual M GT with the smooth, automatic shift transitions that allow drivers to focus entirely on the V12's sound and the road ahead without attention to gear selection. The automatic transmission's torque converter provides a slight cushioning effect at low speed that makes the M GTA particularly refined in traffic and on relaxed touring routes where stop-and-go conditions would make a manual car more demanding. Suspension maintenance with correct bushings and fresh dampers provides the same handling improvement on the M GTA as on the manual car, since the chassis engineering is identical between the two M-body variants. The updated M body's revised aerodynamics and styling do not alter the fundamental handling character, maintaining the near-50/50 weight distribution and balanced cornering behavior of the front-engine rear-transaxle layout.

What automatic transmission service is required for the Ferrari 456 M GTA?

The GM automatic transmission in the 456 M GTA requires fluid and filter changes at 30,000-mile intervals or when shift quality begins to deteriorate, and using the correct ATF specification is essential for maintaining solenoid and valve body function. High-mileage or long-stored M GTA cars often benefit from a more thorough valve body service to restore firm, consistent shift points that can become soft or inconsistent as internal seal material ages and contaminates the fluid. The transmission control module on later 456 M GTA cars is occasionally a source of shift quality issues and can be tested and replaced if fluid and valve body service alone does not restore correct transmission behavior.

How does the 456 M GTA differ from the original 456 GTA in terms of parts?

The 456 M GTA and original 456 GTA share the same GM automatic transmission and fundamentally the same 5.5-liter V12, meaning drivetrain and engine service parts are broadly interchangeable between the two generations. The significant differences are in exterior body components, where the M's revised headlights, bumpers, and body moldings are not interchangeable with the original 456 GTA's exterior parts. Interior components also differ with the M's updated switchgear and trim, and confirming the specific generation of your car is necessary before sourcing any exterior or interior items.
